ISI 'Excellent in all areas' INSPECTION REPORT 2023

We are delighted to announce that Charterhouse Square has been judged by the ISI to be ‘excellent in all areas’.

In April 2023, ISI inspectors examined both our compliance and educational standards. In an exceptionally thorough process, Parents, staff, and Upper House children were invited to complete questionnaires, over 70 lessons were observed, and the majority of staff were interviewed in some capacity. In addition, children’s books, teacher’s planning and all school procedures and policies were scrutinised.

Charterhouse Square School has achieved the highest category of ‘excellent’ in both areas ‘quality of pupils’ academic and other achievements’ and ‘quality of pupils’ personal development’. In addition, all eight areas of the compliance inspection were met.

This judgement is a testament to the hard work and dedication of our teaching teams and recognises what a very special place Charterhouse Square is.


In 2016, Charterhouse Square School was judged to provide an outstanding education for its pupils. The SIS noted:
The quality of education is outstanding as are pupils’ learning and achievement.
Teaching and assessment and the curriculum are also outstanding.
There is a clear focus on promoting the academic achievement of pupils and the school does this exceptionally well. The school also gives its pupils a full and rounded education within which they have ample opportunities to take part in a very wide range of competitive and recreational sports and to develop their creative and musical talents.

Pupils’ spiritual, moral, social and cultural development is outstanding as is their personal development. The school promotes the welfare, health and safety of its pupils exceptionally well.
The leadership, management and governance of the school are outstanding. They are highly effective, and ensure that all of the independent school standards are met.

"The effectiveness of the Early Years Foundation Stage is also outstanding, thereby enabling the youngest children to make excellent progress. "

Pupils make excellent progress in their development of knowledge, skills and understanding. This is as a result of well-planned lessons and high expectations of teachers.
